Its 2 normally-open and 2 normally-closed instantaneous contacts handle 10 A at AC-12 duty (resistive loads), with rated breaking capacities of 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V.
The 10 A AC-12 rating is the maximum continuous resistive load the contacts can carry. For inductive loads like small relays or contactor coils, derate per the AC-15 or DC-13 curves — the 24 V DC rating of 10 A is for resistive; at 110 V DC the rating drops to 1 A, and at 220 V DC to 0.27 A. The 6 kV surge voltage resistance means the contactor withstands typical switching transients without breakdown, important for panels near motor starters or VFDs. The shock resistance of 10g for 5 ms and 5g for 10 ms covers most industrial vibration from conveyors or compressors. The DC coil holding at 3.2 W means a 24 V DC supply needs only about 133 mA continuous per contactor — a 2 A supply can feed roughly 15 of these units simultaneously.
